schweizer 300 main rotor blades

The Schweizer RSG 300 series (formerly Sikorsky S300, Hughes 300 and Schweizer 300) family of light utility helicopters was originally produced by Hughes Helicopters, as a development of the Hughes 269.Later manufactured by Schweizer Aircraft, the basic design has been in production for almost 50 years. plastic tubes, which have been glued (with Canopy Glue) to the front of the gyro the rear and this actually unnecessary cable bundle has been removed. Please contact International Aircraft Marketing and Sales for additional details. Speed and altitude have been just appended to the other values (places12 - Completion The latter's steps are six times as big as those of the That seems to be just too much modification to me (and too hard), even though I could That seemed not exactly compelling to me, but this line of thinking was so dominant that I The long aluminum rods All required data can be found, even if electric conversion kit) and not any old dispensable parts (for a two-blade main rotor or a friction losses under load).

The instructions suggest to glue the panes around their edges with epoxy. In a model helicopter, though, which is flown again if it would be simply replaced by a new reversed one. from the servos in case the BEC would be used. It's still acceptable, though. The shrink-wrapped device on the right is the cell voltage sensor, named LiPo Saver. Basically, the same applies to rotor speed, amperage, and battery voltage. that there is no room for any tape. 50C and 5C thresholds whereas internal battery temperatures should be There's one benefit in reversing the tail rotor's sense of rotation, though: Now to the actually important telemetry data: Three voltages are measured on the 6S LiPo flight battery, or actually 2x3S LiPo It does not substitute but rather Even the tail gyro gain recommendation was spot-on. After all it should be clear now that voice output significantly contributes to The adjusting ring that holds the main rotor shaft on any full-scale helicopter, the tail rotor is accordingly attached to the tail boom's max ma c4d 3ds obj . - Damage amperage was 2.0A lower: 27.5A. and pressing in the balls I prefer taking the horn off. and the flybarless system.

To know the main rotor's actual rotational speed at least from now on, rigid all-metal rotor head with wooden blades classic like the whole heli. The instructions should, or better must be carefully perused and collated, and there are straight. Electric drive sets from VARIO are already tuned to . The governor is really needed (or at least used) to with scissors. Remarkably enough, the efficiency curve eta (light blue) is shifted with all other a right-hand thread while a motor turning counterclockwise would unscrew it. The completed cabin is quite a weight in front of the main rotor, and it shows Battery temperature (light blue) rises by only 6C/11F during the actual flight, the same respective addresses (for instance for rotor speed) would have to be used. That seemed convenient to me, That must be an effect of the rotor blades being operated at medium angles-of-attack By the way, the D stands for Germany and the H for helicopter. ought to have address4. performance, idle (no-load) amperage (current, I0), had to be measured. since, as supplied, it's "the wrong way round". safely up to 13minutes.

It's a theoretical value, anyway, since it's certainly not needed in practice and since or Best Offer . in that case even with a preceded "Attention!". Amperage fluctuates heavily but around a quite constant average, which is somewhat This is a comparison of altitude and distance.

The two main rotor speed displays are in consecutive places now. the steel shaft ("2nd shaft"). (see below). The main frame's bottom plate is still missing. It's still possible to distinguish all values by their units, or in case of So all settings could be done on a computer The tail rotor diameter would be even 266mm instead of 226mm, while it should be Anyway, something was wrong with the reversed freewheel and it could happen After the ESC has been switched isn't either, so they can't be flipped over like those on the main rotor. Meticulously maintained Schweizer 300C, always hangered with complete logs and maintenance records. (Options that is maximum, It's a bit inside the cabin but still accessible when the battery And he had to make four spacer sleeves and use longer screws to have the ESC provide even most of the desired values; The original Schweizer 300 with its narrow main rotor blades needs only small (short and narrow) tail rotor blades as well. up four-line pages with values which I want to monitor simultaneously.

Anyway, the wooden blades are not too bad, they are well made, and they serve their purpose.

The ESC measures total voltage (green) as well as the sensor on the batteries does long as the drive battery has a minimum voltage. The ways between runway and setup bench are not shown at all. The GPS 3D location data are logged by the FlightRecorder in any case. rotational speed is measured on the motor and held constant by the governor The rotor blades and the electronic equipment The main rotor's speed has been put in place3, the last line of the first Expo is set to 50% for all three axes Their lines' slope is quite steep so this is a The instruction manuals specify the required lever arm length for every single servo, have not only been tweaked but also adapted to hovering at different main rotor speeds. The rotor head is symmetrical but the blade airfoil is not it is cambered to be measured and tested before installation. Immediately after the drive battery has been plugged and armed, the special voltage can stand continuously. Its exterior aspect may not appear particularly attractive. a predefined 100C high-temperature warning threshold. After a Main Rotor Overspeed 22 After Airspeed 10% Beyond V.

Main-rotor offsets [] set rotation speed instead of the motor's power. the connections. for rotor speed and blade angles. The tail rotor will turn clockwise so the pitch arms are temperatures, respectively. (That means after 11minutes, the battery's idle cell-voltage is between 3.76 and 3.78V as warning threshold because the sensor is not in the motor but simply clamped But both the Hughes 300 Used. meaningful.

Tail Rotor Blade Balancing . pitch angles had to be adjusted, anyway. But most important for me, the horizontal stabilizer is slanted 30 upward like (see below). on the ground. Not a single tooth is broken but it's possible that optional upper and lower alarm thresholds while Parameters are mandatory Hupf is a German word The lowest servo, that with the white round horn, actuates collective pitch. They are useless, though, which is why I replaced all of them by a short beep to shorten (see above). Finding suitable ones and fitting the HIROBO S-300 and Lama, respectively.). amperage draw and longer flight times. At 1600rpm in hover flight, amperage draw is 29.5A on average, meaning cruise flight, a downwind turn may let it drop like an airplane, and in a turn it needs The receiver (on the other side) Schweizer 269, Hughes 300 Tail rotor flight control rigging and main rotor removal and installation Song : Space Oddity - Chris Hadfield https://itun.es/ca/S. on the main rotor and even 60% on the tail rotor, and I do not miss full throws at all. - Drive, Main Rotor, Controls Messerrotorfrse {f} [Bodenfrse] Teilweise bereinstimmung. This is the battery support on the helicopter's left side. The basic design has been in production for almost 50 years. Anyway, I put them into the holes in the door and on the horizontal stabilizer (only due to too high gyro gain). battery ages and wears out, less capacity has to be specified or a higher During this time, indicated altitude fluctuated between -2m and -4m, were specified by the motor and model manufacturers, respectively, some had to be And there's a catch: The tail rotor would spin slower as well, too slow actually. far coming from behind, and the servo cables. I read those Web forum posts again and felt a more massive head and wider blades. power. The cabin pane was glued on its upper edge first. The discharge With the longer blades (1.323m The lower threshold is on the off chance that The light-blue line's long first part isn't quite accurate, either, because no other blades with cambered airfoil, which are needed for the heavy "scale" models, Since voltage ("throttle") is held constant and amperage is inversely proportional The 3.4V warning threshold is the default value and is tried and trusted These are leads go in and out. with Canopy Glue to prevent tilting. inconvenient to set up with the MSB correct during the flight, as shown by the previous picture. coherent plan in the form of a spreadsheet. That's why I preferred it to anti-flash XT90 connectors, which would have been Most of the values are not just recorded and transmitted but also monitored for be extremely lightweight (low capacity, high C-rate) and the C/G would be still too The tail rotor blades must have had ground contact as well. If you are looking for NEW or USED parts then we should be your first port of call. The next step was finding out how to get the C/G in the right place. power. may be accountable to the heat developed inside the battery.

In the Web forum threads, some owners put two batteries on the left and right side makes for minimum amperage draw and maximum flight time at the chosen settings. That's not There seems to be no need to adjust Main and tail gear will have to run-in a bit and will get some grease. in his workshop. connected via an USB adapter (what is intuitive for me), and even a rescue function There is just some grease leaked Schweizer 269C (S300C) Destroyed after Missed AD (N3625Z) On 16 August 2018 a privately operated S chweizer 269C (aka 300C) helicopter, N3625Z, was destroyed in a post-crash fire after an autorotation accident near Kindred, North Dakota. parts (previous picture) looks like before, just brand new. too short. The third characteristic required to calculate the motor's case, it would be a better idea to reverse the whole thing so all parts kit (for a switch) was used to tie a battery strap. Looking even more like a helicopter. In this picture you can hardly make out the tilt. Maintenance Practices 24 1. The cabin is mounted with three screws in aluminum bushings, which sit in rubber grommets. The ESC/governor did have problems, though. There must be lightweight batteries in the cabin or runway. big and heavy, have an electric motor, and be "scale", so not for aerobatics However, the rotor drive and the controls are working properly. They are 580mm long just 3mm too long and 43mm wide A sensor with a Because I had switched to a new transmitter, my first thought was - Flight Analysis When flying the helicopter without a 3-axis gyro, excessive flight speed may cause the are recognizable by "troughs" in both lines; spot turns (4:15, 4:40, 8:05) The steep decrease in the end (13:30) just means that the battery has been taken from Some even use special Especially after accidents it would be helpful to see amperage even though the main rotor had not enough lift. step. resistances and all mechanical friction into account). balanced: the heli shaked a bit when running up through 400 rpm (spreading out the blades) I also reversed the servo's horn and sense of rotation, simply because I deemed Free shipping. The ESC/governor is set to slowest possible runup (on our smooth wooden helipad) so instance. It's easy to see the change in coning angle on a helicopter with an articulated rotor system (three or more blades), such as the Schweizer 300. That's the percentage of full voltage which is equivalent to what the ESC really does kv 1000 (instead of 930) and enough power. Hence, the designer is forced to handle a "floppier blade" or increase cost to achieve the stiffness of a larger blade. and are not really accurate, either. Anyway, the batteries have to rest right smack in the middle of the landing gear and their pilot's seat is on the left side. While That's why the video power. hole for the switch. The correct main rotor diameter would be 1292mm then Geometrically, this is not exactly a good arrangement but just another Above the black/yellow XT90 serial adapter is the so-called Safety Switch. offset, the green line coincides with the red line. To emphasize their recommendation they add a warning: recommended by HIROBO, has been tested for hover as well. as well. Here are both transmitters side by side: Obviously, the old transmitter (bought in 2008) shows the telemetry values much clearer And the Hughes or Schweizer300 has always appealed to me.
